kafka stream client shutdown

Question

I have an apache kafka streams application . I notice that it sometimes shutsdown when a rebalancing occurs with no real reason for the shutdown . It doesn't even throw an exception.

Here are some logs on the same

[2022-03-08 17:13:37,024] INFO [Consumer clientId=svc-stream-collector-StreamThread-1-consumer, groupId=svc-stream-collector] Adding newly assigned partitions:  (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)

I'm suspecting its because there are no newly assigned partitions in the log below

[2022-03-08 17:13:37,024] INFO [Consumer clientId=svc-stream-collector-StreamThread-1-consumer, groupId=svc-stream-collector] Adding newly assigned partitions:  (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)

However I'm not exactly sure why this error occurs . Any help would be appreciated.
